One of the most electrifying and controversial athletes ever to step onto the baseball diamond shares the untold story of his rise to fame and fall from grace, including a never-before-seen look behind the curtains into the history, dangers, truths, and lies about baseball's dark secret: steroids.

When Jose Canseco burst into the Major Leagues in the 1980s, he changed the sport-in more ways than one. No player before him possessed his mixture of speed and power, which allowed him to become the first man in history to belt 40+ home runs and swipe 40+ bases in the same season. He won the Rookie of the Year, the MVP award, and a World Series ring. He was a dynamo on the field, and a magnet for trouble off it. From his frequent run-ins with police, to his wild and often highly public love life, Canseco broke the mold of the big-time athlete and ushered in a new era of super-athletes with outrageous salaries and rock-star lifestyles. But behind the gaudy stats and the glitz and glamour of his public life, Canseco cultivated a dark secret, one that would alter the game of baseball and the way we view our heroes forever. Canseco made himself a guinea pig of the blossoming performance-enhancing drugs movement that was only just beginning to take hold in Major League Baseball. Anabolic steroids, human growth hormones-Canseco mixed, matched, and experimented to such a degree that he became known throughout the league as "The Chemist." He passed his knowledge on to trainers and fellow players, and before long performance-enhancing drugs were running rampant throughout the league.

Today, this issue has crept out of the closet and burst into the headlines as players balloon to herculean proportions and hundred-year-old records are not just broken, but demolished. In this shocking autobiography, Canseco sheds light on a life of dizzying highs and debilitating lows-and also provides the answers to questions about steroids and the Major Leagues that millions of sports fans are only now beginning to ask.
